★ Measure three-phase phase/line voltage, zero sequence voltage, voltage/current imbalance, frequency, three-phase current, zero sequence current, power factor, active/reactive/apparent power, forward and reverse active/reactive energy, peak/valley/flat/peak time energy, total harmonic content and 31st harmonic component of three-phase current/voltage
★ Equipped with overcurrent protection, overvoltage protection, undervoltage protection, phase loss and imbalance protection, and zero sequence overcurrent/overvoltage protection
The function of measuring electrical parameter curves includes current curves and active power curves (which can be synchronized with RTU units for communication)
Synchronize the collection of current curves and active power curves at the "dead point" position of the DI point of the command or this product
★ Standard CT, PT or voltage direct input, suitable for various wiring methods
★ Energy metering: active energy (kWh), reactive energy (kvarh)
★ Wide range AC/DC universal power supply: AC/DC85V～265V
★ 1 independent DC24V output interface
★ Equipped with 1 RS-485 communication interface (Modbus RTU communication protocol or DL/T645-1997 protocol)
★ 3-channel switch remote signaling input
★ 1-channel power limit protection relay control output
★ 1-channel power limit alarm relay control output
★ Comprehensive display: A row of ten LED displays, used for displaying electricity measurement data and motor protection actions, and can be modified through display and buttons, including instrument address, CT ratio, communication baud rate, protection setting and time limit (with a step size of 0.1S);
★ Demand statistics: maximum, minimum, and average electricity consumption, and analysis of the balance of the pumping unit
★ SOE event recording: 32 SOE event sequence records, recording events such as phase loss, overcurrent, overvoltage, undervoltage, three-phase imbalance, remote signal displacement, and clean energy
★ Measurement of 31st harmonic components of current/voltage
★ Electric power diagram: Collect more than 200 points of electric power diagram data per stroke, including current and active power
★ Time of use billing function: 10 time periods can be preset through RS-485 communication, including peak, off peak, valley, and flat types. Unspecified time periods default to flat
★ Demand statistics function: Statistics of the maximum, minimum, and average values of parameters such as three-phase current, total active power, total reactive power, and total power factor. The statistical period (5-60 minutes, step size: 1 minute) can be set
